Best Heating Systems in Old Houses (Updated)

post img

When it comes to heating systems old houses often have limited options. Their design, layout, existing systems, and construction pose a challenge for any HVAC contractor. These factors often complicate installation as well as temperature control. In this blog, we’ll discuss heating systems old houses use to gain comfort from room to room.

Boiler Heating Systems in Old Houses

When modern indoor heating first made its way to homes, radiator systems were quite common. Many homes built in the 18th century, such as Cincinnati’s many beautiful historic residences, have this equipment.

Radiator systems use a boiler to heat water. It pumps hot water through a network of pipes to radiator units in various living areas. When the hot water heats the radiator’s metal surfaces, they emit radiant heat to the surrounding areas. This is especially helpful to combat heat rising to the high ceiling heights in older homes.

To improve the performance and efficiency of radiators and boilers, repairs and upgrades are often necessary. In many cases, existing radiators remain in good condition. All they need is to install a new boiler to deliver reliable, more efficient heating.

New technology such as modulating-condensing boilers deliver improved efficiency ratings over older boiler equipment. These modern units only heat the amount of water necessary for the home’s heating needs instead of all the unit’s water at once.

Ductless Heating Systems in Old Houses

As far as it goes for heating systems, old houses weren’t built to allow room for ductwork because it didn’t exist at the time of construction. This means to add forced air cooling and heating systems, old houses need major renovations to add the distribution system needed to move conditioned air throughout the home.

In addition to the expense and disruption to the household, owners of older homes often prefer to avoid detracting from the home’s original looks, so the reduction in ceiling heights and other construction to add and conceal ducts is a no-go.

The heating systems old houses often choose today are ductless, so there is no need for ducts at all! Ductless heating systems, or ductless mini splits, are heat pumps. They consist of an outdoor condenser linked to one or multiple indoor air handlers through a small line set.

Instead of a noisy, inefficient window unit, ductless air handlers require only a three-inch hole in the wall. This connects the electrical and refrigerant lines to the outdoor AC compressor. This preserves the aesthetics of the home. It also speeds up installation compared to traditional ducted systems.

Homeowners choose to install the air handlers on the wall or ceiling of the rooms or zones they choose. Depending on the model, up to six air handlers may connect to a single outdoor AC compressor. Using remotes, homeowners control heating and cooling output independent of each other.

Because of this zoned heating system, old houses reduce utility costs thanks to higher efficiency equipment and targeted usage. These systems also deliver cooling, which adds the efficient air conditioning capabilities most older homes go without!

Why Choose Ductless Heating and Cooling Systems?

Ductless systems are quiet, effective, and energy efficient, and they don’t interfere with a home’s architecture. A duct free option also offers the comfort of a modern cooling system without the unsightly look of window AC units.

A ductless system brings certain benefits to older homes:

  • Fits into any home, no matter its age or configuration. Heat and cool many rooms with a different temperature set. One bedroom prefers 68 degrees at night? Another prefers 72? No problem. Set different units or zones at custom levels.
  • The openings needed in each room are minimal and unobtrusive. Installation involves a small round opening or a slotted one, whichever works best in a given room.
  • The high velocity stream of air efficiently heats or cools a room. Air comes out silently so there’s no intrusive noise.
  • Bring humidity levels down within the home. High humidity levels often damage architectural features, furniture, and flooring; plus, it makes living in the home uncomfortable. People with respiratory and certain cardiac conditions suffer greater symptoms when humidity is out of control. Ductless systems bring humidity levels down by as much as 20 percent.
  • Ductless keeps drafts down to a minimum. The gentle release of air from a ductless HVAC unit eliminates drafts common with window AC units.
  • Ductless systems are very efficient, which considerably lowers energy costs. Most models are ENERGY STAR certified.

Other Heating Systems for Older Homes

Other heating systems old houses use are high-velocity heating and cooling systems. This is a type of central HVAC system that requires ductwork, but the ducts are much smaller than the standard ducts installed in newer homes. These “mini-ducts” are more easily concealed and are able to run through narrow and existing spaces in the home.

Depending on the old house’s layout and construction, this is one of the simplest options. Because the ducts are smaller, the HVAC equipment moves air through with a greater velocity. Be advised, this creates some noise as the system runs.
